I'll be honest, I struggled to find 5 romances I got THAT invested in. Maybe I'm forgetting some obvious stuff or have missed some series but I did barely think of 5.

5. Satou and Misaki (Welcome to the NHK): The romance part is probably the least interesting thing about their relationship, but it's there, and right at the end of the anime is quite genuine and touching. If there's any way I'd want to see a sequel, that'd be the direction I'd go. I guess.
4. Satou (but a girl this time!) and Takagi (Detective Conan): Like every couple in this series, it's more that their interactions are fun, and this couple usually has the best stories (especially in the first half of the anime) and it was nice to see a couple in this series actually officially be a couple for once. Also helps that the characters are pure fun (or as fun as a murder mystery show allows I guess?)
3. Sousuke and Kaname (Full Metal Panic!): This was a decently done romance in the high school anime style but then THAT HAIR CUTTING SCENE WHY DID THAT WORK SO WELL?! I can't describe why I like this one so much but Second Attack, especially the middle of that season, was kind of amazing.
2. Syaoran and Sakura (Tsubasa): Oh boy this manga. All I'll say is, I wish the entire series was as good and heart-warming as the final volume.
1. Ikuru and Ai (Ai-ren): This manga will never be remotely known, even for manga communities on the internet. It's a shame since the main romance of the story is incredibly well done. It is genuinely beautiful and is the closest a manga has come to making me cry. This series is just filled with emotions that even much of my favorite series could not match. Wonderful manga.

5. The Queen's Sword - It was nice to finally not feel absolutely helpless in ICO, that and this sword is just cool looking.
4. The Material Blades ( The Vorpal Sword and Flamberge) - I really like the symbolism behind these swords (I can't explain it for spoilerey reasons.), they allow Lloyd to use his mystic arte, I love dual swords, and they look great.
3. The Granasaber - If you've played Grandia II, you know why this sword is cool. (Saying anything about this sword is spoilery.)
2. Ragnell (Couldn't find any good pictures of it in game.) - Aside from being insanely overpowered, completely unbreakable, and a ranged weapon, it just looks awesome.
1. The Monado (This one in particular.) - A sword with a fantastic backstory, and unique look that has endless abilities that come with it? Of course it's awesome.
